FLAME ARRESTER Filed June 14, 1928 Patented Apr. 22, 1930 f ,UNITED STATES PATENT osFrcE MILES F. YOUNT, F BEAUMONT, TEXAS FLAME .ARRESTER Application filed June 14,

provide an eflicient flame arrester which is r so constructed that it will not fail either in its flame arresting function or in its venting function, due to action thereon of heat, the.

0 elements or the fumes of the stored oil.

A further object of the invention is the provision of a novel and improved vent, cap or hood reventing the entrance of rain or dust to the upper end of the vent, which is so constructed that in event the vented gases become ignited, the hood is moved out of thepath of the flame, so that it will not be destroyed thereby.

A further object of the invention is to provide'a device of this character which may be readily and cheaply manufactured, which will be durable and efficient in service and a general improvement in the art. These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a vertical sectional view through a flame arrester constructedvin accordance with my invention;

Figure 2 is a section on the line 2-2 of Figure 1; I

Figure 3 is an enlarged detail sectional View on the line 3-3 of Figure 2. 1 1

Referring now more particularly to the drawing, the numeral 10 generally designates the body of a vent, this body preferably having at its outer end a vertically directed portion 11. Adjacent the terminal of the body, the body is formed with an internal rib 12 upon which is seated a grating 13 of any" suitable material. Ihis grating directly supports a screen 14 upon which is arranged an aggregate 15 consisting of some non-fusible,

non-corrosive material. Pebbles may be conveniently employed for this purpose,'as-.metallic elements must be avoided, for the reason" that the fumes of the oil, when acting upon metallic elements,.would cause the same to 1928. Serial N0. 285,397.

corrode and rapidly choke the spaces therebetween, so that the device would fail as a vent. If desired, a second screen 16 may be superimposed upon the aggregate and held in position by a grate 17. In event the grate 5 17 is employed, the straight portion 11 of the body is preferably provided with a second shoulder 18, which is notched at intervals and the grate is provided with lugs 19 to enter the notches and which, after entering, may be positioned beneath the rib by a slight rotation thereof. The upper end of the vent body is provided at one side with a pivot 20' and at its opposite side with an eye 21.

Pivoted upon the pivot 20 is a hood 22 having secured thereto an arm 23 upon which is mounted a counterweight 24 of suflicient size to constantly urge the hood to an open position where it parallels the vent outlet and' v I is accordingly disposed out of the path of flame arising therefrom. This hood has an eye 25 which is connected to the eye 21 of the vent mouth by a fusible wire 26. It will be obvious that in event the gases arising from the vent become ignited, the heat of the flame-will burn the fuse wire, so that the I bias weight 24.- will move the hood to its open position. 1

It will be obvious that a device of this character may be very readily and cheaply manufactured and may be readily applied to the oil tank without any change in the structure thereof. With such a vent may be associated the usual snulfers, valves or other accessories, as desired. While I have above 3 stated that the grate and screen may be formed of any suitable material, it will, of course, be understood that these elements are preferably constructed of a suitable noncorrosive material. The screen, in many instances, may comprise merely larger elements ofthe aggregate.

Since the construction employed may ob-. viously be modified to a certain extent without materially departing from the spirit of the invention, I do not limit myself to such specific structure" except as hereinafter claimed. t

I claim Y 1. A gas vent for oil tanks comprising a hollow body having a screen therein, a pivoted hood covering the outer end of the body, means constantly urging said hood to one side of the body and a fusible member main- 5 taining said hood in its operative position against the action of said means.

2. A'gas vent for oil tanks comprising a hollow body having a screen therein, said body at its end having pivoted thereto at one side a hood disposable to cover said end and prevent the entry of rain or dust thereto, an arm secured to said hood and having a weight thereon constantly urging the hood to a position where it is disposed at one side of the end of the body and coacting ears upon the hood and the opposite side of the body having engaged therewith the opposite ends of a fuse wire.

3. A gas vent for oil tanks comprising a hollow body having a screen therein, a hood covering the outer end of the body and mounted u on the body for outward movement, and fusi le means retaining said hood in its operative position. 5 In testimony whereof I afiix my signature.
